Bardic Presence
Feat
Prerequisites: Bard
Strange things happen to you and those you travel with. This can get someone out of a tricky spot, or make a good day even better.
When you or another creature you can see gets involved in any kind of situation, you can choose to roll a d20 and add your Charisma modifier to determine to what degree the outcome of the situation is changed. Anything higher than or equal to 15 will have a positive effect on the situation, anything lower than or equal to 5 might have negative implications, and anything inbetween won't cause any changes.
You can use this feature a number of times equal to your Charisma modifier (a minimum of once). You regain any expended uses when you finish a long rest.
